KEBAFLOW LCP MF235 (FE 200302*)

KEBAFLOW LCP MF235 is a high heat resistance LCP reinforced with 35% short glass fibers. The material is characterized by the following properties: Good flowability at thin wall thicknesses, very good toughness and strength, inherent flame retardancy, high heat deflection temperature (HDT /A = 255°C), good chemical resistance. Compared to other LCP grades, KEBAFLOW MF235 exhibits significantly improved weld line strength.



LCP - KEBAFLOW

Details

The trade name KEBAFLOW stands for a range of liquid crystalline polymers (LCP). KEBAFLOW’s outstanding flowability enables the realization of extremely thin wall thicknesses. KEBAFLOW LCP is inherently flame retardant and exhibits very high heat resistance and good aging behavior.

Pre-drying:

Dryer type: dry air dryer.
Temperature: 150 – 170°C
Drying time: 4-6 h
Residual moisture: < 0.01%.

Temperatures:

Melt temperature: 335 – 345°C
Mold temperature: 80 – 120 °C

Dosage:

Shot volume = 50-80% of the maximum metering volume.
Back pressure: very low (0 – 30 bar spec.)
Dosing time: Corresponds approx. to cooling time

Injection unit:

Screw: 3-zone screw with non-return valve
Nozzle: Open nozzle or shut-off nozzle (recommended)
Wear protection: Wear and corrosion protected according to the machine manufacturer’s recommendation for LCP glass fiber reinforced

The most important processing instructions in brief:

– Ensure good drying! Ensure moisture content < 0.01%.
– Inject as fast as possible, if necessary use machine with pressure accumulator.
– Injection speed has a strong influence on the achievable flow path length
– Avoid excessively thick walls
– Ensure good venting
